Salmonella in Tuna Sushi Sickens 9 in Arizona

A Salmonella paratyphi outbreak linked to raw tuna sushi has sickened nine people in Arizona, three of whom have been hospitalized, according to the Maricopa County Department of Public Health (MCDPH). Several other states are investigating outbreaks of the same strain including California and New Mexico.

Arizona health officials say a rare strain of Salmonella paratyphi in raw minced or ground tuna used to make spicy tuna rolls and other sushi is the likely source. The nine Maricopa County cases reported onset of illness between April 3rd to April 16th.

“We are early into the investigation, but from the interviews we have completed with those who have gotten sick, there are multiple restaurants involved,” said Dr. Bob England, director of Maricopa County Department of Public Health. “That is strong evidence that the contamination is occurring before it gets to the restaurant.”

In California, at least 25 cases have been reported. In New Mexico, six.

Health officials urge anyone who has eaten sushi or other foods containing raw ground sushi and develops symptoms of Salmonella poisoning which include nausea, diarrhea and abdominal cramping to seek medical attention and mention possible exposure. “Healthcare providers are advised to get stool cultures from patients presenting with diarrhea and fever,” England said.
